When changing the Settings on your detector, please keep in mind: Each time the unit is turned On the factory settings of Highway and Auto Mute-On will be set. They can be changed while the unit is in use as described in the following sections.
Assistance Muting An Alert
Your detector allows you to quickly turn Off an audio Alert by momentarily pressing the Mute button. If you press the Mute button a second time during the Alert, the audio Alert will be turned back On.
Auto Mute Mode
Auto Mute will automatically reduce the audio volume of all alerts after four (4) seconds for as long as the signal is detected. The factory setting for Auto Mute is On.
Setting your detector to City mode delays all X band audio alerts at lower signal strength levels. (A single beep will sound when the signal is first Notice detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers. To change settings, follow the procedure listed below, which indicates what you will see and hear as you complete each step. The factory setting is Highway mode.
Mute Button Press and release

City Button Press and release
Press and release the Mute button while no alert is occurring.
When radar detectors proved easily capable of sniffing out radar from miles away, radar gun manufacturers responded by producing instant-on radar or unoffically called "Pulse" radar. In the instant-on mode, the radar's transmitter is placed on hold, ready to fire but not yet producing a signal for detectors to hear. The officer waits until his target is very close (brings a new meaning to "wait till you see the whites of their eyes") then releases the radar from stand by mode and gets a speed reading within a second or so (pulse). In this situation, no detector offers much warning.
There are guns out there that operate just like the instant-on guns of the past but with a very tough twist - POPTM mode! This gun is a normal K and Ka band radar gun detectable by most radar detectors made in the past 30 years, until this gun is placed in POP mode. When the gun is in POP™ Mode and activated, a brief burst of energy, less than 1/15 of a second, is transmitted and the vehicle's speed is quickly acquired. A detector without POP™ Mode detection capability cannot respond to this brief transmission. TIP - When traveling in unfamiliar highways always try to find a vehicle which is traveling at the same rate or faster than you are and keep several car lengths behind them. This way the other vehicle can "flush out the radar".
I was using one of these for the last 8 months, and mine did the same thing, I would push power and the unit will just blink the lights then shut off, But if I hold the power button the light will stay on until the button was released, so I contacted Solo Tech support and they told me the system control board was bad, and in order to get a new board I had to be an authorized servicer for then, I found the board online and the price for the board exceded the price I paid for it. So i deemed it necessary to just purchase a new Scanner....
Police usually do not leave their radar guns turned on all of the time. Indeed, most police officers prefer to use the "instant-on" technique to nab speeders. Instant-on works by leaving the radar gun in standby mode (no radar emissions) and then releasing a trigger button to instantly turn on the radar gun to measure a vehicle's speed.
You can check to see if your radar detector is detecting radar by putting it in Highway mode and then driving to a shopping center or other businesss location which has microwave radar automatic door openers. You should get either X band or K band alerts for these microwave automatic door openers. If you do not get any alerts for these door openers, and after having checked a few other locations which have microwave automatic door openers, then this would indicate that your radar detector is defective.
This is most likely caused by a poor connection between the antenna ridge and the local oscillator board. Another possibility is an uncontrolled LO chamber harmonic due to the cold temperatures. Regardless of the cause, your V955 is under warranty and Bel will fix it for free -- as long as you include a photocopy of your sales receipt. Go to Bel's web site (www.beltronics.com), and either call their 800 number or do the online chat in order to get a RMA number.
OK.....this is strange. I have the same problem with constant false alarms switching between POP and KA for five to ten minutes constantly. I tried the Q tip recommendations from this site and no luck. Here's the weird part, when pluged into my 2006 Lexus GS the problem continued. When I plug it into my new used car a 2006 Mercedes CLK it works perfect! So, my conclusion is it must be a combination between the dector and the Lexus that causes the problem. I'm confused because it took over a year and a half for the problem to start in the Lexus. I plan on calling Escort tech dept. to see what the heck would cause this.I'll post the results from the call afterwards.
I too had the same problem and called their customer service. They told me 1 chirp means a front receiver fault, 2 chirps means a rear receiver fault. They suggested I check the wiring and to switch the front receiver with the back receiver to see if the error code would "travel" with it to determine if the receiever was faulty. I did that and the problem went away. I assume I had a connection that loosened up.
